What fuel is used in hydrogen fuel cells
Fuel cells can promote energy diversity and a transition to renewable energy sources. Hydrogen — the most abundant element on Earth — can be used directly. Fuel cells can also utilize fuel containing hydrogen, including methanol, ethanol, natural gas, and even gasoline or diesel fuel. Fuels containing hydrgoen generally require a “fuel reformer” that extracts [...]
Benfits of hydrogen fuel cells
New Markets. Fuel cell power system markets could exceed $3 billion worldwide by 2000, according to a recent Arthur D. Little, Inc., study.
* A mere one percent of the global vehicle market, 450,000 vehicles, would mean an another $2 billion or more.
* Another recent study projected global demand for transportation fuel cells in 2007 at [...]
hydrogen fuel cells
In principle, a fuel cell operates like a battery. Unlike a battery, a fuel cell does not run down or require recharging. It will produce energy in the form of electricity and heat as long as fuel is supplied.
A fuel cell consists of two electrodes sandwiched around an electrolyte. Oxygen passes over one electrode and [...]

Sony’s (SNE) senior vice-president, Mike Abary, explained that defects “aren’t even the top three reasons for returns.” The top reason? The products “didn’t meet expectations.” According to the article, an Accenture report shows that it costs the U.S. electronics [...]
Miscanthus as a biofuel
In the largest field trial of its kind in the United States, researchers have determined that the giant perennial grass Miscanthus x giganteus outperforms current biofuels sources – by a lot. Using Miscanthus as a feedstock for ethanol production in the U.S. could significantly reduce the acreage dedicated to biofuels while meeting government biofuels production [...]
Life Sciences
In research that likely has implications for creating intelligent hearing aids, researchers have discovered that a frog that lives near noisy springs in central China can tune its ears to different sound frequencies, much like the tuner on a radio can shift from one frequency to another. It is the only known example of an [...]
Copper nanowires used in long lasting displays
A new low-temperature, catalyst-free technique for growing copper nanowires has been developed by researchers at Illinois. The copper nanowires could serve as interconnects in electronic device fabrication and as electron emitters in a television-like, very thin flat-panel display known as a field-emission display.“We can grow forests of freestanding copper nanowires of controlled diameter and length, [...]
